MOUNTING RECOMMENDATIONS
CONNECTING WIRES
• Wires should be fastened to the other wires or non-
moving parts. Try to avoid heat emitting and moving
objects near the wires.
• The connections should not be seen very clearly. If factory
isolation was removed while connecting wires, it should
be applied again.
• If the wires are placed in the exterior or in places where
they can be damaged or exposed to heat, humidity, dirt,
etc., additional isolation should be applied.
• Wires cannot be connected to the board computers or
control units.
CONNECTING POWER SOURCE
• Be sure that after the car computer falls asleep, power is
still available on chosen wire. Depending on car, this may
happen in 5 to 30 minutes period.
• When module is connected, measure voltage again to
make sure it did not decrease.
• It is recommended to connect to the main power cable
in the fuse box.
• Use 3A, 125V external fuse.
CONNECTING IGNITION WIRE
• Be sure to check if it is a real ignition wire i. e. power does
not disappear after starting the engine.
• Check if this is not an ACC wire (when key is in the rst
position, most of the vehicle electronics are available).
• Check if power is still available when you turn o any of
vehicles devices.
• Ignition is connected to the ignition relay output. As
alternative, any other relay, which has power output
when ignition is on, may be chosen.
CONNECTING GROUND WIRE
• Ground wire is connected to the vehicle frame or metal
parts that are xed to the frame.
• If the wire is xed with the bolt, the loop must be
connected to the end of the wire.
• For better contact scrub paint from the spot where loop is
going to be connected.
Connecting the power supply must be carried out
in a very low impedance point of on-board vehicle
network. Connecting the GND at an arbitrary
point to the mass of the car is unacceptable, as
static and dynamic potentials on the line GND
will be unpredictable, which can lead to unstable
FMB965 operation and even its failure.
PAY ATTENTION!
